LT1469-2  
Dual 200MHz, 30V/µs  
16-Bit Accurate A ≥ 2 Op Amp  
V
FEATURES  
DESCRIPTION  
The LT®1469-2 is a dual, precision high speed opera-  
tional amplifier with 16-bit accuracy, decompensated to  
be stable in a gain of 2 or greater. The combination of  
precision and AC performance makes the LT1469-2 the  
optimum choice for high accuracy applications such as  
DAC current-to-voltage conversion and ADC buffers. The  
initial accuracy and drift characteristics of the input offset  
voltage and inverting input bias current are tailored for  
inverting applications.

200MHz Gain Bandwidth Product  
30V/μs Slew Rate  
Settling Time: 800ns (150ꢀV, 10V Step)  
Specified at 5V and 15V Supplies  
Maximum Input Offset Voltage: 125μV  
Low Distortion: ꢀ96.±dB for 100kHz, 105  
P-P  
Maximum Input Offset 5oltage Drift: 3μ5/ꢁC  
Maximum Inverting Input Bias Current: 10nA  
Minimum DC Gain: 3005/m5  
Minimum Output Swing into 2k: ±12.ꢂ5  
Input Noise 5oltage: ±n5/√Hz  
Input Noise Current: 0.6pA/√Hz  
The 200MHz gain bandwidth ensures high open-loop gain  
at frequency for reducing distortion. In noninverting ap-  
plications such as an ADC buffer, the low distortion and  
DC accuracy allow full 16-bit AC and DC performance.  
The high slew rate of the LT1469-2 improves large-signal  
performance in applications such as active filters and  
instrumentation amplifiers compared to other precision  
op amps.  
Total Input Noise Optimized for 1kΩ < R < 20kΩ  
Available in ꢂ-Lead Plastic SO and

12-Lead (4mm × 4mm) DFN Packages  
APPLICATIONS  
The LT1469-2 is specified on power supply voltages of  
±±5 and ±1±5 and from ꢀ40ꢁC to ꢂ±ꢁC. It is available in  
an ꢂ-lead SOIC package and a space saving 4mm × 4mm  
leadlesspackage.Foraunity-gainstableopampwithsame
